Description

本発明は、水洗大便器に係り、特に、洗浄水を旋回させることにより汚物を排出する水洗大便器に関する。 The present invention relates to a flush toilet, and more particularly to a flush toilet that discharges filth by swirling the wash water.

従来から、洗浄水を吐水してボウル部に旋回流を形成する吐水部を、ボウル部の前側領域に設け、この吐水部から吐水した洗浄水をボウル部内で旋回させて汚物を排出するようにした水洗大便器が知られている。このタイプの水洗大便器は、ボウル部の前側領域に設けられた吐水部から洗浄水を吐水することにより、ボウル部の後側領域に比べ曲率半径の小さい前側領域でのエネルギー損失を抑え、旋回流の水勢を維持させることにより、ボウル部の洗浄不良を防止するようにしている。 Conventionally, a water discharge part that discharges wash water to form a swirling flow in the bowl part is provided in the front region of the bowl part, and the wash water discharged from this water discharge part is swirled in the bowl part to discharge filth. Washing urinals are known. This type of flush toilet bowl suppresses energy loss in the front region, which has a smaller radius of curvature than the rear region of the bowl, by discharging the wash water from the spout provided in the front region of the bowl, and swivels. By maintaining the water force of the stream, poor cleaning of the bowl portion is prevented.

例えば、特許文献１に記載された水洗大便器においては、水洗大便器の後部上方に設けられた貯水タンクから、ボウル部の上端に設けられたリム部の内部を通過し、リム部の前側領域に開口したリム吐水口に至り、このリム吐水口から前方に向けて洗浄水を吐水し、ボウル部に旋回流を形成し、汚物を排出するようにしている。 For example, in the flush toilet described in Patent Document 1, a water storage tank provided above the rear portion of the flush toilet passes through the inside of the rim portion provided at the upper end of the bowl portion, and the front region of the rim portion. It reaches the rim spout that opens in the rim, and the washing water is spouted forward from this rim spout to form a swirling flow in the bowl part so that filth is discharged.

特許第５５８５９４４号公報Japanese Patent No. 5585944

しかしながら、特許文献１の水洗大便器では、ボウル部後方側からリム吐水口へと洗浄水を供給するため、リム部の内部にリム吐水口へと洗浄水を導くリム導水路を形成する必要がある。このため、リム部の設計自由度やデザインが制限され、これに伴い、水洗大便器全体の設計自由度やデザインが制限されるおそれがある。 However, in the flush toilet of Patent Document 1, since the wash water is supplied from the rear side of the bowl portion to the rim spout, it is necessary to form a rim headrace that guides the wash water to the rim spout inside the rim portion. be. For this reason, the degree of freedom in design and the design of the rim portion are limited, and accordingly, the degree of freedom in design and the design of the entire flush toilet bowl may be limited.

さらには、ボウル部後方側からリム吐水口へと洗浄水を供給するため、リム導水路内部の空気が洗浄水により引きずられ、異音が発生するおそれがある。この異音は、リム導水路が長くなればなるほど、空気量も増加するため、発生しやすい。例えば、リム導水路が後方領域から延びてボウル部の前端のリム部を経由する場合に、リム導水路の長さが大きくなるため、リム導水路内部の空気量が増加し、これに伴い、空気の分離に起因する異音がより発生しやすいという課題がある。 Further, since the washing water is supplied from the rear side of the bowl portion to the rim spout, the air inside the rim headrace may be dragged by the washing water and an abnormal noise may be generated. This abnormal noise is likely to occur because the longer the rim headrace, the larger the amount of air. For example, when the rim headrace extends from the rear region and passes through the rim portion at the front end of the bowl portion, the length of the rim headrace is increased, so that the amount of air inside the rim headrace increases. There is a problem that abnormal noise due to air separation is more likely to occur.

本発明は、上述した課題を解決するためになされたものであり、リム部の構造による水洗大便器全体の設計自由度やデザインへの影響を抑制し、さらに、異音の発生を抑制することができる水洗大便器を提供することを目的としている。 The present invention has been made to solve the above-mentioned problems, and suppresses the degree of freedom in designing the entire flush toilet and the influence on the design due to the structure of the rim portion, and further suppresses the generation of abnormal noise. The purpose is to provide a flush toilet that can be used.

次に、上述した本発明の一実施形態による水洗大便器１の作用を説明する。
使用者によりスイッチ等を押圧することにより洗浄開始操作がなされた場合、まず、貯水タンク２０に貯水された洗浄水が加圧ポンプ２２により加圧され、第１導水ホース２６を通ってリム導水路１０に供給される。 Next, the operation of the flush toilet bowl 1 according to the above-described embodiment of the present invention will be described.
When the cleaning start operation is performed by pressing a switch or the like by the user, first, the cleaning water stored in the water storage tank 20 is pressurized by the pressurizing pump 22, and is passed through the first water guiding hose 26 to the rim headrace. It is supplied to 10.

リム導水路１０に供給された洗浄水は、リム導水路１０の内部の空気を攪拌しながら、リム吐水口１２へ向かい、リム吐水口１２からリム部８の内周面に沿って後方に向けて吐水される。この洗浄水が汚物受け面６上を反時計回りに流れる旋回流となり、汚物受け面６を洗浄する。 The washing water supplied to the rim headrace 10 heads toward the rim spout 12 while stirring the air inside the rim headrace 10, and is directed rearward from the rim spout 12 along the inner peripheral surface of the rim portion 8. Water is spit out. This washing water becomes a swirling flow that flows counterclockwise on the filth receiving surface 6, and cleans the filth receiving surface 6.

その後、第１導水ホース２６への洗浄水の供給が停止され、このとき、加圧ポンプ２２に設けられた逆止弁３０により、洗浄水は第１導水ホース２６に残存する。次いで、加圧ポンプ２２は第２導水ホース２８により洗浄水をジェット吐水口１４に供給し、ジェット吐水口１４から吐水される。 After that, the supply of the wash water to the first water guide hose 26 is stopped, and at this time, the wash water remains in the first water guide hose 26 by the check valve 30 provided in the pressurizing pump 22. Next, the pressurizing pump 22 supplies wash water to the jet spout 14 by the second water guide hose 28, and discharges the washing water from the jet spout 14.

次に、本発明の一実施形態である水洗大便器１により奏される効果について説明する。
本実施形態による水洗大便器１においては、リム吐水口１２がボウル部４の前側領域に位置するリム部８に設けられ、そのリム吐水口１２から、洗浄水を吐水し、この洗浄水がリム部８に沿って旋回してボウル部４の汚物受け面６を洗浄し、リム導水路１０がボウル部４の前側領域に位置するリム部８の内部に設けられ、リム吐水口１２へ洗浄水を導き、第１導水ホース２６により、ボウル部４の汚物受け面６の下方の空間を経由してボウル部４の前側領域に位置するリム導水路１０の上流端に洗浄水を供給すると共に洗浄水供給停止時には逆止弁３０により第１導水ホース２６の内部に洗浄水が残るようになっている。その結果、リム導水路１０の長さを短くすることができ、それにより、リム部８の設計自由度及びデザインが制限されることを抑制することができる。従って、リム部８の構造による水洗大便器１全体の設計自由度やデザインへの影響を抑制することができる。さらに、例えば、ボウル部４の後側領域からボウル部４の前端にまでリム部８内部にリム導水路が延びている場合に比べ、リム導水路１０が短くなるので、リム導水路１０内部の空気量を軽減することができ、それにより、洗浄する際に洗浄水に空気を巻き込むことにより発生する空気の分離に起因する異音の発生を抑制することができる。 Next, the effect produced by the flush toilet bowl 1 according to the embodiment of the present invention will be described.
In the water-washing toilet bowl 1 according to the present embodiment, the rim water spouting port 12 is provided in the rim portion 8 located in the front region of the bowl portion 4, and the washing water is discharged from the rim water spouting port 12, and the washing water is discharged from the rim. The sewage receiving surface 6 of the bowl portion 4 is washed by swirling along the portion 8, and the rim headrace 10 is provided inside the rim portion 8 located in the front region of the bowl portion 4, and the washing water is sent to the rim spout 12. Is guided, and the first headrace 26 supplies wash water to the upstream end of the rim headrace 10 located in the front region of the bowl portion 4 via the space below the filth receiving surface 6 of the bowl portion 4 and cleans the toilet portion 4. When the water supply is stopped, the check valve 30 allows the washing water to remain inside the first headrace 26. As a result, the length of the rim headrace 10 can be shortened, whereby the degree of freedom in design and the design of the rim portion 8 can be suppressed. Therefore, it is possible to suppress the degree of freedom in design and the influence on the design of the entire flush toilet bowl 1 due to the structure of the rim portion 8. Further, for example, the rim headrace 10 is shorter than the case where the rim headrace extends inside the rim portion 8 from the rear region of the bowl portion 4 to the front end of the bowl portion 4, so that the inside of the rim headrace 10 The amount of air can be reduced, and thereby it is possible to suppress the generation of abnormal noise caused by the separation of air generated by entraining air in the cleaning water during cleaning.

また、本実施形態による水洗大便器１においては、通常、空きスペースとなる排水トラップ管路１６の左右及び下方に貯水タンク２０が配置されるので、水洗大便器１全体の設計自由度及びデザイン自由度を向上させることができる。また、貯水タンク２０がボウル部４の後方に設けられる場合と比べ、貯水タンク２０が配置される位置をリム導水路１０に近づけることができるため、第１導水ホース２６をより短くすることができ、第１導水ホース２６内の空気に起因する異音が生じることを抑制することができる。 Further, in the flush toilet bowl 1 according to the present embodiment, since the water storage tanks 20 are usually arranged on the left, right, left and right and below the drain trap pipeline 16 which is an empty space, the degree of freedom in design and the design freedom of the entire flush toilet bowl 1 are free. The degree can be improved. Further, as compared with the case where the water storage tank 20 is provided behind the bowl portion 4, the position where the water storage tank 20 is arranged can be brought closer to the rim headrace 10, so that the first water guide hose 26 can be made shorter. , It is possible to suppress the generation of abnormal noise caused by the air in the first headrace 26.

また、本実施形態による水洗大便器１においては、排水トラップ管路１６の出口を外部の配管（図示せず）に接続する排水ソケット１８と貯水タンク２０とが一体に設けられているので、貯水タンク２０と排水ソケット１８との隙間が小さくなり、このため、排水トラップ管路１６の左右及び下方の空きスペースをより有効に利用することができ、さらに、水洗大便器１全体の設計自由度及びデザイン自由度を向上させることができる。 Further, in the flush toilet bowl 1 according to the present embodiment, the drainage socket 18 and the water storage tank 20 for connecting the outlet of the drain trap pipeline 16 to an external pipe (not shown) are integrally provided, so that water can be stored. The gap between the tank 20 and the drain socket 18 is reduced, so that the empty spaces on the left, right, and below of the drain trap pipe 16 can be used more effectively. The degree of design freedom can be improved.

また、本実施形態の水洗大便器１においては、第１導水ホース２６の下流端がリム導水路１０の底面に形成された接続用開口１３に接続され、第１導水ホース２６によりリム導水路１０内へ上方に向けて洗浄水が供給されるようになっているので、リム導水路１０内の空気を洗浄水により攪拌することができ、それにより、リム導水路１０内における空気の分離に起因する異音の発生をより効果的に抑制することができる。 Further, in the flush toilet bowl 1 of the present embodiment, the downstream end of the first headrace 26 is connected to the connection opening 13 formed on the bottom surface of the rim headrace 10, and the rim headrace 10 is connected by the first headrace 26. Since the washing water is supplied upward inward, the air in the rim headrace 10 can be agitated by the washing water, which is caused by the separation of the air in the rim headrace 10. It is possible to more effectively suppress the generation of abnormal noise.

以上、本発明の実施形態を説明したが、上述した実施形態に種々の変更を加えることができる。例えば、貯水タンク２０及び加圧ポンプ２２を設ける代りに、水道供給圧を利用し、水道から直接第１導水ホース２６を介してリム導水路１０に洗浄水を供給するようにしてもよい。 Although the embodiments of the present invention have been described above, various modifications can be made to the above-described embodiments. For example, instead of providing the water storage tank 20 and the pressurizing pump 22, the water supply pressure may be used to supply the washing water directly from the water supply to the rim headrace 10 via the first headrace 26.
